Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidifying devices, and particularly relates to a humidity control device. Background Art

[0002] Museum display cases are used to display cultural relics. Cultural relics are precious and vulnerable, and are sensitive to humidity. When the humidity in the display case is too high, it is easy for metal cultural relics such as bronze to rust. When the humidity is too low, it is easy for fiber cultural relics such as woodenware and paper to crack, which is not conducive to the protection of cultural relics.

[0003] In order to better preserve cultural relics, a humidity regulating device is usually set up to adjust the humidity inside the display case. The existing humidity regulating device usually divides the inside of the device into a humidifying chamber and a dehumidifying chamber by an electrolyzed water film layer, and connects the humidifying chamber and the dehumidifying chamber to the inside of the display case to control dehumidification or humidification through a built-in power module. Among them, the working principle of the electrolyzed water humidity regulating film assembly to regulate humidity is as follows: after the built-in power module applies a voltage, water vapor on the anode side is ionized at the anode to generate oxygen, hydrogen protons and electrons. The hydrogen protons pass through the electrolyte membrane, and the electrons reach the cathode through the circuit; at the cathode: oxygen, hydrogen protons and electrons in the air recombine to generate water vapor, realizing the function of water vapor transfer, so as to achieve the purpose of regulating the environmental humidity. Because it is difficult to improve the humidity regulating efficiency of the film layer per unit area in the electrolyzed water humidity regulating film assembly, if it is necessary to improve the humidity regulating ability of the device, it is generally achieved by increasing the area of the electrolyzed water humidity regulating film assembly.

[0004] However, a larger membrane area is not only inconvenient for use in scenarios with limited space, but also reduces energy efficiency, thereby increasing the use and manufacturing costs. Summary of the Utility Model

[0037] Embodiment 1:

[0038] As Figures 1 to 7 shown, in this embodiment, a humidity control device 10 includes: a device body 100 and at least two electrolytic water membrane assemblies 200 for electrolyzing moisture; the device body 100 is provided with at least one installation opening 130, and the electrolytic water membrane assemblies 200 are respectively arranged on two opposite sides of the installation opening 130; the device body 100 is further provided with a first channel 110 and a second channel 120, the first channel 110 is arranged inside between the two electrolytic water membrane assemblies 200, and the second channel 120 is arranged outside the two electrolytic water membrane assemblies 200; the electrolytic water membrane assembly 200 includes an electrolyte membrane 240 and anode plates 220 and cathode plates 230 arranged on both sides of the electrolyte membrane 240, and the polarities of the adjacent plates between the two electrolytic water membrane assemblies 200 are the same.

[0039] Specifically, reference is made to Figures 1 to 3, the first channel 110 is disposed between two second channels 120, such that from top to bottom, one second channel 120, the first channel 110, and the other second channel 120 are sequentially arranged at intervals. Every two electrolyzed water membrane assemblies 200 are installed in an installation opening 130, and both ends of the installation opening 130 are provided with grooves that cooperate with the electrolyzed water membrane assemblies 200 to respectively accommodate the two electrolyzed water membrane assemblies 200. By sealing both sides of the installation opening 130 with the electrolyzed water membrane assemblies 200, the air flow exchange between the first channel 110 and the second channel 120 needs to pass through the electrolyzed water membrane assemblies 200. And the electrolyzed water membrane assemblies 200 at the upper and lower ends include cathode plates, electrolyte membranes 240, and anode plates. The electrolyte membrane 240 is disposed between the anode plate 220 and the cathode plate 230, and the anode plate 220 and the cathode plate 230 are optionally but not limited to being arranged in a frame shape, so as to expose as large an area of the electrolyte membrane 240 as possible for operation; between the electrolyzed water membrane assemblies 200 at the upper and lower ends: the polarities of adjacent plates are the same, that is, the polarities of the plates close to the first channel 110 are the same, so that the electrolyzed water membrane assemblies 200 can perform the same work at both ends simultaneously. In addition, the humidity control device 10 can also be provided with a wireless control module to control the power supply mode of the electrolyzed water membrane assemblies 200 through the wireless control module, realizing remote control of the humidity in the display cabinet. At the same time, the electrolyzed water membrane assemblies 200 can effectively avoid the appearance of liquid water in the display cabinet and are suitable for a variety of different usage scenarios.

[0040] It should be noted that by relatively arranging at least two electrolyzed water membrane assemblies 200 and setting the polarities of adjacent plates between the two electrolyzed water membrane assemblies 200 to be the same, the first channel 110 and the second channel 120 that are isolated from each other and respectively perform the functions of humidification and dehumidification are formed. This device can achieve higher humidity adjustment efficiency in a smaller volume, not only has a higher space utilization rate, but also can improve the energy efficiency of the device and reduce the use and manufacturing costs.

[0041] Such as Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, in some embodiments, the first channel 110 is set as a humidification channel, the second channel 120 is set as a dehumidification channel, and the cathode plates 230 between the electrolyzed water membrane assemblies 200 at both ends are adjacently arranged.

[0042] Specifically, the cathode plates 230 are all arranged close to the first channel 110, and the anode plates 220 are all arranged away from the first channel 110. In this way, when in use, a DC voltage is applied to both the cathode plates 230 and the anode plates 220. The cathode plates 230 are connected to the negative electrode of the power supply through conductive sheets, and the anode plates 220 are connected to the positive electrode of the power supply through conductive sheets. On the side of the anode plates 220, water molecules in the gas in the second channel 120 are electrolyzed into oxygen and hydrogen ions, realizing dehumidification of the gas in the second channel 120; under the action of the current, hydrogen ions in the gas or electrolyzed from the anode plates 220 migrate through the electrolyte membrane 240 to the side of the cathode plates 230. The hydrogen ions on the side of the cathode plates 230 react with the oxygen in the environment of the first channel 110 to regenerate water vapor, realizing humidification of the gas in the first channel 110. In this way, the dehumidification and humidification effects of the humidity control device 10 can be adjusted to control the humidity of the museum showcase to maintain a constant humidity inside.

[0043] In another embodiment, the installation method of the electrolytic water membrane assembly 200 can be adjusted, that is, the anode plates 220 between the electrolytic water membrane assemblies 200 at both ends of the installation port 130 are arranged adjacent to each other, that is, the anode plates 220 are all arranged close to the first channel 110, and the cathode plates 230 are all arranged away from the first channel 110. Thus, the first channel 110 is set as a channel for dehumidification, and the second channel 120 is set as a channel for humidification.

[0044] It can be understood that the specific setting relationship between the anode plates 220 and the cathode plates 230 can be determined according to actual usage requirements and is not limited here.

[0045] Embodiment 2

[0046] This embodiment is a further implementation manner of Embodiment 1. In this embodiment, the device body 100 is provided with at least two installation ports 130, and the number of electrolytic water membrane assemblies 200 corresponds to the number of installation ports 130.

[0047] Specifically, the number of installation ports 130 is set to at least two, and the number of electrolytic water membrane assemblies 200 is set to twice the number of installation ports 130. The number of electrolytic water membrane assemblies 200 can be selected but is not limited to four, eight, and twelve. In this embodiment, referring to Figure 5 , the number of installation ports 130 can be set to four, and the number of electrolytic water membrane assemblies 200 is correspondingly set to eight.

[0048] To make the adjustment effect better, such as Figure 5As shown, in some embodiments, at least two first channels 110 are provided. The two first channels 110 are relatively independent of each other and can be arranged in parallel, intersecting, or staggered manners, so as to improve the contact effect between the film layer and air in the first channels 110 as much as possible, ensure the humidification or dehumidification efficiency in the first channels 110, and enhance the humidity regulation effect of the device.

[0049] For example, when the electrolytic water membrane assembly 200 is provided with four, two first channels 110 are provided, and the two first channels 110 can be arranged side by side, surrounded to form a ring, arranged in a staggered manner, etc.; for another example, referring to Figure 5 , in this embodiment, when the electrolytic water membrane assembly 200 is provided with eight, the first channels 110 can be provided as two side-by-side ones, and every four electrolytic water membrane assemblies 200 are connected to one first channel 110. It can be understood that the two first channels 110 can also be surrounded to form a ring, arranged in a staggered manner, etc.; for still another example, when the electrolytic water membrane assembly 200 is provided with twelve, two first channels 110 are provided, and every six electrolytic water membrane assemblies 200 are connected to one first channel 110, and the two first channels 110 are arranged side by side, surrounded to form a ring, arranged in a staggered manner, etc.

[0050] Furthermore, each first channel 110 is connected to at least two mounting ports 130. For example, referring to Figure 5 , in this embodiment, when the electrolytic water membrane assembly 200 is provided with eight, each first channel 110 is connected to two mounting ports 130; for another example, when the electrolytic water membrane assembly 200 is provided with twelve, each first channel 110 is connected to three mounting ports 130.

[0051] In addition, the layout of the first channels 110 can also be set otherwise. For example, the number of the first channels 110 can also be set as three, four, etc. arranged side by side, or the first channels 110 can be connected to four mounting ports 130, etc., as long as air intake and exhaust can be carried out uniformly for each first channel 110.

[0052] Of course, the number and arrangement mode of the first channels 110 can be determined according to the actual situation. The purpose of different arrangement modes is to improve the humidity regulation effect as much as possible. The above cases do not limit the arrangement mode thereof, and no redundant description is made here.

[0053] In some embodiments, the electrolytic water membrane assembly 200 and the mounting port 130 are detachably connected.

[0054] Specifically, by detachably connecting the electrolytic water membrane assembly 200 and the mounting port 130, it is convenient to replace the electrolytic water membrane assembly 200 when it is damaged. Among them, the detachable connection mode can be selected but is not limited to common detachable connection modes such as screwing, clamping, and bonding.

[0055] In some embodiments, every two electrolyzed water membrane assemblies 200 disposed at both ends are arranged oppositely.

[0056] Specifically, the two electrolyzed water membrane assemblies 200 disposed at the upper and lower ends are arranged facing each other, and the two electrolyzed water membrane assemblies 200 disposed at the upper and lower ends form a membrane group, so that the substances during electrolysis are more concentrated, thereby further improving the adjustment efficiency. For example, when the number of electrolyzed water membrane assemblies 200 is four, two membrane groups are formed. Another example, referring to Figure 5 , in this embodiment, when the number of electrolyzed water membrane assemblies 200 is eight, four membrane groups are formed. The first channels 110 can be set to two in parallel. Every two membrane groups are communicated with one first channel 110, and the four membrane groups can be arranged in a rectangular array optionally but not limited to, such as a circular array, which can make the gas content inside the device body 100 more; Another example, when the number of electrolyzed water membrane assemblies 200 is twelve, six membrane groups are formed.

[0057] In order to facilitate the use of the first channel 110 and the second channel 120, in some embodiments, the included angle range formed by the first channel 110 and the second channel 120 is: 0° to 360°.

[0058] Specifically, the included angle range formed by the first channel 110 and the second channel 120 is set according to actual production requirements:

[0059] In one embodiment, the included angle formed by the air flow directions of the first channel 110 and the second channel 120 is 180°, that is, the air flow directions of the two channels are opposite.

[0060] In another embodiment, the included angle formed by the air flow directions of the first channel 110 and the second channel 120 is 360°, that is, the air flow directions of the two channels are the same.

[0061] Among them, the air flow directions of the first channel 110 and the second channel 120 are arranged in a staggered manner:

[0062] Referring to Figure 2 , Figure 3 and Figure 5 , in this embodiment, the included angle formed by the first channel 110 and the second channel 120 is 90°. In this way, the included angle formed by the air flow direction of the first channel 110 and the air flow direction of the second channel 120 is arranged perpendicular to each other, so that the components of the first channel 110 and the second channel 120 communicating with the outside can be arranged staggeredly, and it is more convenient to use, occupies less space, and makes the overall integration of the humidity control device 10 better and the practicability better.

[0063] In another embodiment, the included angle formed by the first channel 110 and the second channel 120 is 45°. In this way, the components through which the first channel 110 and the second channel 120 communicate with the outside can also be staggeredly arranged, occupying less space, and making the overall integration degree of the humidity control device 10 better.

[0064] In yet another embodiment, the included angle formed by the first channel 110 and the second channel 120 is 270°.

[0065] It can be understood that by adjusting the included angle relationship of the air flow direction between the first channel 110 and the second channel 120, the distribution of the internal channels and structures of the humidity control device 10 can be optimized, and the product integration degree can be improved to better adapt to different usage scenarios.

[0066] For the convenience of connecting to the display cabinet, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, a first intake pipe 111 and a first outlet pipe 112 are provided on the device body 100. The first intake pipe 111 is communicatively connected to the first outlet pipe 112 through the first channel 110. A second intake pipe 121 and a second outlet pipe 122 are provided on the device body 100. The second intake pipe 121 is communicatively connected to the second outlet pipe 122 through the second channel 120.

[0067] Specifically, a first intake pipe 111 and a first outlet pipe 112 are provided on the outside of the device body 100. The first intake pipe 111, the first channel 110, and the first outlet pipe 112 are sequentially communicatively connected. A second intake pipe 121 and a second outlet pipe 122 are provided on the outside of the device body 100. The second intake pipe 121, the second channel 120, and the second outlet pipe 122 are sequentially communicatively connected. In this way, when the first channel 110 and the second channel 120 cooperate with the corresponding electrolytic water membrane module 200 to work, referring to Figure 2 , the gas to be humidified can be introduced into the first channel 110 through the first intake pipe 111, and the humidified gas in the first channel 110 can be discharged through the first outlet pipe 112; referring to Figure 3 , the gas to be dehumidified is introduced into the second channel 120 through the second intake pipe 121, and the dehumidified gas in the second channel 120 is discharged through the second outlet pipe 122. Thus, the display cabinet can be externally connected through a pipeline. If the device is damaged, it is also convenient to repair and replace in time, thereby increasing the practicality of the humidity control device 10.

[0068] For the convenience of disassembling and replacing the electrolytic water membrane module 200, as Figure 1 、 Figure 5 and Figure 6As shown, in some embodiments, the device body 100 includes a frame 140, an upper cover 150, and a bottom cover 160. A first channel 110 is defined in the frame 140. A second channel 120 is formed between the frame 140 and the upper cover 150, and another second channel 120 is formed between the frame 140 and the bottom cover 160.

[0069] Specifically, at least two second through-holes 123 are further defined at the upper and lower ends of the frame 140. In this embodiment, four second through-holes 123 are defined at the upper end of the frame 140, and the positions thereof are correspondingly arranged with the position of the first channel 110. Every two through-holes are arranged on one side of the frame 140. A second channel 120 is formed between the outer surface of the frame 140, the four second through-holes 123, and the inner surface of the upper cover 150; four second through-holes 123 are defined at the lower end of the frame 140. Another second channel 120 is formed between the outer surface of the frame 140, the four second through-holes 123, and the inner surface of the bottom cover 160. By forming the second channels 120 between the frame 140 and the upper cover 150 and the bottom cover 160 respectively, it is convenient to disassemble and replace the electrolytic water membrane assembly 200.

[0070] Through the above modular integrated design of the electrolytic water membrane assembly 200 inside the device, when a single electrolytic water membrane assembly 200 fails, it can be replaced in time. Moreover, merchants can increase or decrease the number of the installation openings 130 and the electrolytic water membrane assemblies 200 according to different humidity control requirements, without additionally designing different specifications of the electrolytic water membrane assemblies 200, greatly reducing the design cost and design time of the humidity control device 10. The electrolytic water membrane assemblies 200 with unified specifications can also avoid the problem of high power consumption caused by excessive increase of the membrane material area, improving the product reliability and energy efficiency, and thus reducing the manufacturing and maintenance costs of the product.

[0071] Embodiment 3

[0072] This embodiment is a further implementation manner of Embodiment 1 or 2. As Figure 7 shown, in this embodiment, the electrolytic water membrane assembly 200 further includes an insulating member 210, and the insulating member 210 covers the surfaces of the anode plate 220 and the cathode plate 230 facing away from the electrolyte membrane 240 respectively.

[0073] Specifically, the insulating member 210 is used to insulate the anode plate 220 and the cathode plate 230. The insulating member 210 is preferably made of rubber or plastic, which can not only insulate but also buffer to protect the electrode plates.

[0074] For the convenience of using the insulating member 210, as Figure 7 shown, in some embodiments, the insulating member 210 is provided as two gaskets, and the two gaskets cover the surfaces of the anode plate 220 and the cathode plate 230 facing away from the electrolyte membrane 240 respectively.

[0075] Specifically, the shape of the gasket is adapted to the shapes of the anode plate 220 and the cathode plate 230, so as to exactly insulate the anode plate 220 and the cathode plate 230.

[0076] To facilitate controlling the conduction between the cathode plates 230 and the anode plates 220 of different electrolytic water membrane assemblies 200, as Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, in some embodiments, a conductive component 300 is provided in the device body 100, and each conductive component 300 is used to conduct the cathode plate 230 or the anode plate 220 of at least two electrolytic water membrane assemblies 200 respectively.

[0077] Specifically, each conductive component 300 is provided as two conductive sheets. The two conductive sheets in each conductive component 300 are respectively connected to an anode plate 220 and a cathode plate 230, and are insulated from each other for power-on, and the two conductive sheets are arranged in a cross shape. Of course, only the conductive component 300 connecting the anode plate 220 or only the conductive component 300 connecting the cathode plate 230 can also be used.

[0078] It can be understood that the conductive component 300 can also be provided as other conventional components, and can also be arranged in other shapes, as long as it can be used for electrically connecting the anode plates 220 or the cathode plates 230 of different electrolytic water membrane assemblies 200. No redundant description will be given here. By providing the conductive component 300, the wire harness connection between different electrolytic water membrane assemblies 200 can be reduced, thereby improving the internal integration and conductive reliability of the device.

[0079] To facilitate the installation and positioning of the electrolytic water membrane assembly 200, as Figure 5 and Figure 6 shown, in some embodiments, at least two pressing members 400 are further included. The pressing members 400 are detachably connected to the device body 100; the electrolytic water membrane assembly 200 is fixed at the installation port 130 through the pressing members 400.

[0080] Specifically, the pressing member 400 can be but is not limited to a frame-shaped pressing plate. When the frame body 140, the upper cover 150 and the bottom cover 160 are firmly connected, the pressing member 400 abuts against the conductive sheet and the insulating member 210, and presses and fixes the electrolytic water membrane assembly 200 and the conductive component 300 on the frame body 140. The pressing member 400 can increase the tightness between the electrode plate and the electrolyte membrane 240, reduce the impedance, and also improve the reliability of the detachable connection structure.

[0081] Embodiment 4

[0082] This embodiment is similar to Embodiment 3, the difference being that, as Figures 8 to 9 shown, in this embodiment, the insulating member 210 is provided as an insulating shell that wraps around the anode electrode sheet 220, the electrolyte membrane 240, and the cathode electrode sheet 230, and covers the sides of the anode electrode sheet 220 and the cathode electrode sheet 230 that face away from the electrolyte membrane 240, respectively.

[0083] Specifically, by providing the insulating member 210 as an insulating shell and having a notch to expose the electrical connection point, the insulating effect can be achieved by wrapping.

[0084] It can be understood that the sealing effect of the insulating member 210 in the electrolytic water membrane assembly 200 can be achieved by wrapping or partitioning, and is not limited to the above implementation methods, as long as the electrolytic water membrane assembly 200 can be in an insulating state.

[0085] In the present utility model, unless otherwise clearly specified and defined, terms such as "installed", "connected", "connected to", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0086] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this utility model is usually placed during use.
